Read the work before the total
Read the document as a construction scope before comparing the total. A price is hard to evaluate when quantities, named products, accessories, unknown conditions, exclusions, or responsibilities are missing.
A checklist to use
- Find the measured roof quantity and waste method. Find the measured roof quantity, slope and geometry assumptions, waste method, and whether the proposal distinguishes roof area from floor area.
- Name removal layers and hidden-deck rules. Confirm existing layers, tear-off and disposal, deck assumptions, ordinary sheet unit pricing, and the approval path for structural work.
- Check starter, ridge, underlayment, flashing, and ventilation. Look for starter, ridge, underlayment, self-adhered areas, flashing, pipe boots, ventilation, fasteners, and manufacturer-required accessories.
- Separate exclusions, options, permit, disposal, and contractor fee. Separate excluded work, selectable upgrades, permit handling, protection, cleanup, warranties, contractor compensation, and closeout deliverables.
Compare scope gaps before price gaps
Mark every line that appears in one proposal but not the other, then resolve the difference in writing. Only comparable scopes can show whether one contractor is actually charging less for the same roof.
